After hubs (1) and (2) and holding ring (4) are installed on shafts, the teeth are them aligned parallel to each other, but not touching (fig 1).
Once installed, the hubs never need to be moved again.
The elastic insert (3) can then be installed in the slots formed by the parallel teeth.
When the insert is in position, slide holding ring (4) onto the polyurethane insert starting, centrifugal force will expand the elastic insert to fix it tightly to the inside of the steel ring ( fig 2 ).
As an extra safety it is possible to lock the ring with two locking screws (fig 3).
To disassemble, remove the ring. The insert can then be quickly and easely removed and replaced.
No special tools, screws, bolts ore other fasteners needed.
